This invention relates to a printing press means for cutting oftI anypage individually at the ink fountain so that ink will not be deliveredto thatplate. The principal object of the means for cutting ofi' anypage at will independently of the blade adjusting means. The means.provided is of such a nature that the adjustment of the blade will berestored to its exact-original position when the cut-olf means isreleased. v

Other objects and advantages vention will appear hereinafter.

Reference is to be had to the accompanying drawings in which 4 Fig. 1 isa side view of an inking device for printing press partiallydiagrammatic in orm;

Fig. 2 is a, plan of the regulating means partly in section; and

Fig. 3 is an enlarged transverse sectional view.

It has been customary to provide the ink fountain for a newspaperprinting press with a blade which scrapes the surplus ink from of theini the surface of the fountain roll. The desired thickness of the filmof inkA on thesurface of the fountain roll to be delivered to the ductorroll has been regulated by thumb screws arranged at regular intervalsalong the length of the blade. Heretofore when it was desired to cut offall `the ink from that portion of the fountain roll which supplies anentire page, it has been customary to tighten all of the above-mentionedscrews opposite that section of the lfountain blade and to fasten itdown through the desired length. Being employed for one particular partof the cylinder, this necessitated the loss of the adjustment of thesescrews and their re-adjustment whenever it was desired to feed the inkto that page again. This invention is devised for the purpose of easilycutting ofi" the ink from one or more pages without stopping theoperation of the press, if desired, and without interfering withthe-adjustment of the blade for ordinary printing work.4 In other words,after a printing plate has been cut ofi' by movement of the blade intocontact with the roller to keep the ink from it, the blade can inventionis to provide be let back at will and its original adjustment retained.

I have shown the invention as applied to an ordinary fountain 10, andfountain roll 11 delivering ink to a. ductor roll 12 and then to an inkdrum 18 and from there to the usual plate cylinder 14. On this platecylinder are a series of plates 15. Each plate is the width of a pageordinarily so that in the form illustrated a web is printed four pageswide.

A series of blades 17 are located on the stationary back 18, one foreach page of the printed roduct. Each blade is equal to the length o oneof the plates 15. Each blade is adjusted' by a series of thumb screws 19in the usual way so that normally the blade, by its own resiliency, willengage the bottom of its adjusting screws and clear the fountain rolljust enough to allow a film of ink to be delivered i therefrom whichwill give the proper blackness for the particular kind of printingrequired. This obviously can be adjusted at will. No change is made inthis part of the device, as the adjusting screws serve their usualpurpose. Within the back 18 I arrange a series of separate bars 20, eachhaving a. projection 21 extending along the same of the width of one ofthe printing plates or one page of the newspaper. On these bars 20 areformed teeth 22 constituting part of a worm wheel. Each bar is mountedin a recess in the back 18 so that it can turn on its own axis. They areadapted to be turned by a worin 23 individually. This worm has a stem 24and a thumb handle 25 for turning it.

Assume that ,the blades are adjusted so as to give the proper thicknessof ink along the whole width of the press. Now, if it is to be desiredto cut off one page, the worm23 corresponding to that page is turned andthe projection 21 will come down on the blade as shown in Fig. 3 to moveit out of'contact with the adjusting screws -19 and its edge intoContact with the surface of the fountain roll. Now the roll does notdeliver ink in this area. If it is desired afterwards to supply thatparticular area of the plate cylinder, the proper bar 2O is turned backand its projection 21 brought up above the bottom of the siliency,springs back vto engage the bottbms of the screws 19. It will be seenthat its original adjustment is preserved. No re-adjustment of thescrews 19 will be necessary, un-

5 less there is some change which would have required it anyway.

This obviates the necessity of re-adjusting the screws 19 to get exactlythe right film of ink on the roll 11. This is a delicate matter lo yandrequires considerable time ordinarily. The use of this invention resultsin a great saving in time over the methods heretofore` employed.

Although I haveillustrated and described l5 only a single form of theinvention I am aware of the fact that modifications can be made thereinby any person skilled in the art without departing from the scope of theinvention as expressed in the claims.

zo Therefore I do not wish to be limited to all the details ofconstruction herein shown and described, but what I do claim is 1. In aninking device for a printing press, the combination with a fountain rolland a plurality of blades for regulating the thickness of the ink on theroll, of means for adjusting each blade toward or from the roll, andmeans independent of said adjusting means, for moving each blade againstthe roll ao to cut off the ink delivery from the area regulated by thatblade.

2. In an inking device, the combination with a plurality ofblades eachof a length of the width of a printed page for regulating 86 thethickness of the ink on a roll constituting a part of the inking`device, of mea-ns for adjustlng each of said blades toward the roll, andmeans, independent of said adjusting means, for moving each of saidblades independently of any other blade toward the roll to cut oi theink delivery therefrom in the area of a blade thus adjusted, wherebywhen the last-named means has been used and restored, the blade willretain its original adjustment.

3. In an ink supplyin device, the combination with a roll andapilurality of blades for regulating the film of ink delivered thereby,of a series of adjusting screws adapted to enno gage one side of each ofthe blades to regu.-

late the thickness of the film, a plurality of bars, one for each bladeextending along the blades and each bar having a projecting portion, andmeans forlturningV eachof said bars 'I- 65 independently of any otherbar to bring the rojecting portion of said bar against the lilade anddepress it and for turning it back to normal position independently ofsaid adjusting screws. 4. In anink supplying device, the combinafionwith a fountain roll and a plurality of blades one for each sheet, of aseries of adjusting screws adapted to engage one side of each loftheblades to force it toward the roll and regulate the thickness of thefilm of ink on the roll, a plurality of bars extending along the blades,and means for moving each of said bars independently of any other bar todepress a blade away from its adjusting screws and for moving it back tonormal position when the blade will again engage said adjusting screwsand retain its original adjustment.

5. In an ink supplying device, the combination with a roll and aplurality of blades for regulating the film of ink delivered thereby, ofa plurality of bars extending along the blades, each bar having aprojecting ortion, and means for turning each of said ars independentlyof any other bar to bring its projecting port-ion against one of theblades and depress it to cut off the ink supply throughout the length ofsaid bar.

6. In an ink supplying device, `the combination with an ink fountain andfountain roll, said ink `fountain having a back, of a blade su ported bythe back, a series of bars oscillatably carried by said back, each onehaving a length equal to the width of a printed page and each havin'g aprojection thereon of the same length, each bar having worm wheel teeththereon, and operating means for each bar comprising a. worm meshingwith the worm teeth, whereby the projection can be turned into contactwith the blade to cause the blade to engage the roll to cut off theentire supply of ink throughout that area..

7. In anvink supplying device, the combiI nation with an ink fountainand fountain roll, said ink fountain having a back, of a blade supportedby the back, a series of adjusting screws carried by the back forengaging the blade for regulating the thickness of the film of inkdelivered by the fountain roll, a series of bars oscillatably carried bysaid'back, each one having a length equal to the width of a printed pageand each having a projection thereon of the same length, each bar havingworm wheel teeth thereon, and operating means for each bar comprising aworm meshing with the worm teeth, whereby the projection can be turnedinto contact with the blade to cause the blade to engage the roll to cutoff the entire supply of ink throughout that area or to release theblade from its influence and allow it to come back into contact with theadjusting screws.

8. In an ink supplying device, the com- .bination with an ink fountainand fountain roll, said ink fountain having a back, of blades supportedby the back, a series of bars oscillatably carried by said back, eachone having a length'equal to the width of a printed page and each havinga projection thereon of the same length, and operating means for eachbar for forcing the projection into contact with a blade to cause theblade to engage the roll to cut off the entire supply of vink throughoutthat area.

9. In an inking device for a printing press,

the combination with a fountain roll and a blade for regulating thethickness of the ink thereon, of means for adj usting the blade towardor from the roll, and means independ- 5 ent of said adjusting means formoving a portion of the blade against the roll whereby to cut o the inkdelivery from the roll in the area of Contact by thatportion of theblade Y andstill permit delivery of the ink to the 10 remainder of theroll. 10. In an inking device for a printing press, the combination witha stationary back, of a yielding blade carried thereby for engaging lthefountain roll, a sto screw for limiting 5 the distance of the en of thisblade from the fountain roll, an oscillatable barha'ving a projectionthereon for engaging the blade and forcing it down on the fountain rollto out out the part of the roll covered by said 20 blade and to preventink from passing down the blade, said bar having a rack thereon, and aworm for engaging the rack for turning the bar down when desired.
